How to Choose the Right Self Storage Rental Unit Size in Anchorage, AK: A 2026 Sizing Guide

Picking the right self storage rental unit size is one of the most practical decisions an Anchorage renter can make before moving day or a seasonal gear swap. Choose too small and you end up cramming boxes into an unusable pile. Choose too large and you pay for empty floor space every month. This guide walks through the most common unit sizes available for self storage rental in Anchorage, AK, and matches each one to real-life storage situations local residents face year-round.

Common Storage Unit Sizes and What They Hold

Small units work well for light, everyday overflow storage needs. Here is a quick breakdown by size:

5×5 Units (25 Square Feet)

A 5×5 unit is roughly the size of a walk-in closet. It works well for boxes of documents, small furniture pieces, sporting goods, and seasonal clothing. Anchorage residents often use this size to rotate winter gear like ice fishing equipment or cross-country ski accessories when the season ends.

5×10 Units (50 Square Feet)

A 5×10 unit can hold the contents of a small bedroom or studio apartment. Think a mattress set, a few boxes, small appliances, and a dresser. This size is popular for UAA students or downtown Anchorage renters who need short-term overflow during a lease transition.

10×10 Units (100 Square Feet)

A 10×10 unit is one of the most versatile sizes available. It can typically hold the contents of a one-bedroom apartment, including a sofa, bed frame, dining set, and 20 to 30 boxes. Midtown Anchorage and South Addition residents doing a home remodel often find this size covers most of their needs.

10×15 Units (150 Square Feet)

A 10×15 unit adds meaningful extra room for larger households. It can handle the contents of a two-bedroom apartment along with extra furniture and appliances. This size also suits Anchorage homeowners doing a full garage cleanout before the busy summer season.

10×20 Units (200 Square Feet)

A 10×20 unit is comparable to a one-car garage in floor space. It can hold the contents of a three-bedroom home, large appliances, or a full garage's worth of tools and equipment. Anchorage residents storing ATVs, snowmobiles, or a boat for the off-season often look at this size first.

What Size Do I Need for a One-Bedroom Apartment?

A 10×10 unit is typically the right fit for a one-bedroom apartment in Anchorage. It can hold a full bed, sofa, dining table, and 20 or more boxes comfortably when items are stacked carefully.

Anchorage Seasonal Storage Tip

Alaska winters demand extra planning. Anchorage renters should account for bulky seasonal items that need storage space of their own. Winter tires, studded tire sets, sleds, snowshoes, and cold-weather camping gear can fill a 5×5 or 5×10 unit on their own. If you plan to store these alongside household goods, consider sizing up by one unit. Summer gear like kayaks, fishing rods, and hiking equipment also takes up more room than most renters expect.
